On Coruscant
It was a normal day on Coruscant. Citizens of the surface level went about their lives as usual, the thought of danger never even crossing their minds. Because Coruscant was the heart of the Republic, and therefore the safest place one could possibly be. The Revolution was dead, the Sith were exterminated, and the Sith Hunter Rebels were scattered.
Then, one by one, dark vessels appeared in the clear blue sky above. The radiant sun was slowly blotted out by a fleet, no, an armada of clunky capital ships. Soon after, every radio frequency on the planet had been hijacked, and a horrible song was forcibly broadcast on every channel; men and woman screaming words in an unknown language, pounding drums and blowing horns.
In his office, Jorg Sucal looks out in shock as the Republic Defensive Fleet is dwarfed by the enemy. It is obvious that his forces can not prevent these invaders from landing ships on the surface before reinforcements arrive, so he orders the emergency shield generators activated.
Massive bubbles of energy form around the Senate Plaza, Presidential Palace, and other key locations across the planet. That would at least keep ships from landing there or dropping bombs. If they wanted to get to him, they would have to walk.
